    摘要： The process and the apparatus are used for the low-temperature fractionation of air. Charge air (1) which has been compressed and has undergone prior purification is introduced into a rectifier system for nitrogen/oxygen separation. This system comprises a pressure column (2), a low-pressure column (3) and a condenser/evaporator system (101, 102, 103) for heating the low-pressure column (3). The condenser/evaporator system has a first section (101) which is designed as a falling-film evaporator. A first oxygen-rich liquid (6) from the low-pressure column (3) is introduced into the evaporation passages of the falling-film evaporator (101), where it is partially evaporated. In the process, an oxygen-rich vapor (11) and a second oxygen-rich liquid (12) are formed. At least part of the oxygen-rich vapor (11) is returned to the low-pressure column (3). The condenser/evaporator system additionally has a second section (102, 103), which is designed at least in part as a forced circulation evaporator (103). At least some of the second oxygen-rich liquid (12, 13) is passed, by means of a delivery device (14), to the evaporation passages of the second section (102, 103) of the condenser/evaporator system.

    摘要： A process delivers oxygen at a variable flow rate from a distillation system. The process uses a higher pressure column and a lower pressure column. The effects of oxygen product rate fluctuations on the distillation system are reduced by maintaining essentially constant flow rates within the columns. The process also utilizes a first storage vessel and a second storage vessel and includes the following features: liquid oxygen is withdrawn at a substantially constant rate from the distillation column system and at least a portion of the withdrawn liquid oxygen is directed to the second storage vessel; liquid oxygen is withdrawn from the second storage vessel at a variable rate and vaporized in a main heat exchanger against an incoming variable flow rate of air which is condensed to form a liquid air stream and then sent directly to the distillation column system; and liquid oxygen is withdrawn from the distillation column system from the same location where at least one of the liquid air streams is fed to the distillation column system, and at least a portion of the liquid air is directed to the first storage vessel during periods of higher than average oxygen delivery rate.

    摘要： A process and installation for the separation of air in a cryogenic distillation apparatus (24) comprising a distillation column (30, 42) and in which the supplied air is separated to produce a fraction rich in oxygen and a fraction rich in nitrogen as products. The purities of these products are maintained substantially constant during variations of demand of either product or of the flow rate or of the pressure of the supplied air by introducing an excess of liquid rich in nitrogen into the distillation apparatus when the demand for the product or the flow rate of the supplied air increases, and by withdrawing an excess of liquid rich in nitrogen from the distillation apparatus, and storing this liquid, when the demand for the product or the flow rate of the supplied air decreases. The apparatus comprises a medium pressure column (30) and a low pressure column (42) and a reflux conduit (44; 11, 12) which permits a reflux liquid to be withdrawn from the medium pressure column (30) and to be injected into the low pressure column (42).
